My inventionrelates to the class of devices equipped for temporaryattachment to trac- 'tion Wheels to prevent slipping, and j more Vpartioularlyto such'devices as embody lengthwise members in theform ofchains, andc'ros's wise members secured at intervals to and connectingsaid lengthw se members and an object of my invention, among others,isthe'" v provision of means whereby cross'members of standardconstruction maybe provided with means for ready attachment todetachment from the lengthwise members.

One form of an attaching means embodying my invention, and'in theconstruction and use of Whichthe objects herein set out,

as well as others, may be attained, is illus trated in the accompanyingdrawing, "in which- Figure 1 is a view of the ends-of a cross chainequipped with my improvedholder.

. chain and are then bent down by a tool usually supplied for thepurpose to hold them in place. In fact, this" form 0]": construction ofthe end members of a cross-link has come to be standard equipment.

It is thepurpose ofmypresent invention f to make use of this standardform of equip-' ment and to so constructmy improved holder that it maybe readily'attached to the end members of the cr-oss'elink with littlediifi- 3 culty.

To this end'I provide a'snap holder pref erably made of thin resilientmetal and comprising a base'and a spring tongue 9.. The tongue is bentbackwardlyito overlie the base, and as shown in Figure 2 of the drawing.The base comprises a'pad 10 at itsfront tdacComplish this purpose;

end of a' width to overlie the under portions PATENT oFFicEL iof'thehooks 8 to retain theholder inplace. I

:Theibas e isbent downwardly at aipoi nt be tweenthe pad l0 and atongue'support 11 comprising the rear end of the base. Ears 12 fareformed on opposite sides of the support :11 to" underlie the branches 13of the hooks,

and the bend between the base andthe tongue 9f'is narrowed to permitthe-tongue topass upwardly between the branches 13. The tongue isbroadened to a width substantially that of the pad 10, thereby overlyingthe branches 13.

1 This structure when viweaeem the end p'resentsa groove atoppositeedgesof the' holder, the upper sides of the grooves being constituted by theedges oft-he tongue 9 and a the lower parts of the grooves beingconlstituted the pad 10 and ears 12. This enables the holderfto beinserted by a move- 7 ment lengthwiseof the branches-13, which branches'm ay be slightly spread apart as shown in Figure 5 to permit insertionof the holderand may then-be closed toward each other into their normalpositions and in which positions the holder, will; be securely retainedin-place. Thebase of the holder f is preferably of suchv length that itsfront edge willnnderlie the iside part of the linkwj with which the-hookis engaged,and as shown inFigure 2 of the drawing; ,while therear end ofthe base, which also'constitutesfthe rear end of the holder, this'beingthe .bend

attached; 1 j A. It will'be seen from this description, taken inconnection withthe accompanying drawing, that Ihave provided a snapholder between. the tongue and the"ba se, wil1 lie substantially againstthe link ltjof the cross 7 'chainto which the end member or hookB iswhioh may be readily secured [to the hook I of the cross member, of ananti-skid chain with the use of tools, as pliers," readily "at hand.The-holder of such shape and form I that whenfin place it will readilyinaintain,

its position without any shapin'gof the hooks ei g hm the tongue 9 ispreferably :such that whe'n 'li t ng e bent downwardlytit will pass i0-the side -part'ota with' whi'ch- -th .hb kg are to be engaged. Inshort, my improved holder converts a hook of standard construction intoa snap hook.

In accordance with the provisions of the patent statutes I havedescribed the principles of operation of my invention, together with thedevice which I now consider to represent the best embodiment thereof;but I desire to have it understood that the device shown is onlyillustrative, and that the invention may be carried out by other meansand applied to uses other than those above set out. i

I claim: j I V 1. A snap holder for use with anattaching hook comprisingspaced branches having backturned open hooks at one end, said holdercomprising a base and a backturned spring tongue both having lateralextensions oppositely disposed to form, when viewed lengthwise of theholder, grooves opposite edges thereof to receive the branches of saidattaching hook when the latter are closed to normal positions, said basebeing adapted to project through the hook between said branches wherebythe opposite ends of the base rest against the hook on opposite sidesthereof.

2. A snap holder for use with an attaching hook comprising spacedbranches having backturned open hooks at one end, said holder comprisinga base including a broadened pad and extended ears said base beingadapted to project through the hook between said branches, whereby theopposite ends of the base rest against the hook on opposite sidesthereof, and a spring tongue backbetween said branches and having oneend offset from the plane of the opposite end, whereby said oppositeends of the base rest against the hook on opposite sides thereof beingof a length to engage the hooks and the link to which the hooks areattached to prevent substantial endwise movement of the holder.

5. A snap holder for use with an attaching hook comprising spacedbranches having backturned open hooks at one end, said holder comprisinga base having an offset portion whereby the base is adapted to pro jectthrough a hook between said branches from one side to the other sidethereof, clips projecting laterally from the base to engage'a hook, abend in the end of the base adapted to be located between the sidemembers of a hook, and a spring tongue extending from said bend andadapted to lie against said side of the hook at the extreme end of thebase.

3. A snap holder for use with an attaching hook comprising spacedbranches having backturned open hooks at one end, said ho der comprisinga base including abroadened pad and extended ears said base beingadapted to project through the hook between said branches, whereby theopposite ends of the base rest against the hook on opposite]- sidesthereof, and aspring tongue backturned to engage underneath the ends ofthe hooks to which the holder is secured, said tonguebeing broadened toengage the side members of the hook near the base of the tongue. v a a4. A snap holder for'use with an attaching hook comprising spacedbranches .having backturned open hooks at one end, said holdercomprising a base including a broadened pad and a tongue support,aback-turned spring tongue projecting from said support, the bendbetween said tongue and support being narrowed to provide notches toreceive the branches of an attaching hook, said base beingadaptedtoproject through the hook
